It features a 1 inch cutting diameter, a 0.0300 inch corner radius, and 10 flutes for improved chip evacuation and surface finish. The AlCrTiN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other tough materials. With a 3.25 inch length of cut and a 6 inch overall length, this end mill is suited for deep-cavity milling and profile work where reach and rigidity both matter. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers for die and mold work, aerospace component finishing, and precision part production. The micrograin carbide substrate and 40 degree helix angle make it effective in high-speed finishing passes and semi-finishing operations. The straight cylindrical shank with a 1 inch diameter provides secure clamping in ER collet chucks, hydraulic holders, or Weldon-style toolholders. It belongs to the ACCUPRO HS series, which targets extended-reach and high-surface-finish applications in production shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating for thermal stability and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e10-flute geometry improves surface finish and material removal rate\u003c\/li\u003e\n  \u003cli\u003e0.0300 inch corner radius reduces stress concentration at cutting edges\u003c\/li\u003e\n  \u003cli\u003e40 degree helix angle supports smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct upgrade for solid carbide corner radius end mills in the HS series.

Ensure the machine spindle is fully stopped and the tool change procedure follows the machine manufacturer guidelines before mounting or removing the end mill. Verify runout at the toolholder before cutting to protect both the tool and the workpiece. Consult the shop's speeds-and-feeds reference for AlCrTiN-coated carbide at the specific material hardness being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 317309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744544325938,"sku":"317309","price":793.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d1570937ef3c8c9ecb99df508e8540b.jpg?v=1788857863","url":"https:\/\/voomisupply.com\/products\/accupro-317309-corner-radius-end-mill-1in-10-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
